Question
This problem uses Figure 2. Select all that are true about this manometer set-up.

**Diagram Explanation:**
- The diagram illustrates a U-tube manometer connected to a container labeled (A). It contains two different fluids.
- The left side contains a fluid with specific weight \( \gamma_1 \), indicated in blue, and a height \( h_1 \).
- The right side contains a fluid with specific weight \( \gamma_2 \), indicated in red, and a height \( h_2 \).
- Point (1) is at the surface of fluid \( \gamma_1 \) in container (A).
- Point (2) is at the interface between the two fluids inside the U-tube.
- Point (3) is at the bottom of the U-tube, and point (4) is at the open end of the manometer on the right.

**Equations to Select from:**
1. \( P_4 - P_A = \gamma_1 h_1 - \gamma_2 h_2 \)
2. \( P_4 = P_A - \gamma_1 h_1 + \gamma_2 h_2 \)
3. \( P_4 - P_A = \gamma_1 (h_1 + h_2) \)
4. \( P_A = P_1 \)

These options involve calculating pressure differences using the known specific weights of the fluids and the heights in the manometer system.
